exhaust feedback

hey, i need some help with exhaust for a 1974 340 dart swinger. the car has the log style manifolds with the following casting numbers: 4173143-1 passenger side and driver side
4095244. They are stamped date code 84 which i believe they came off a 1984 mopar.
Question, i am looking for the head pipes to hook up a stock style exhaust system. Will the tti head pipes fit? The tti web site does not list my manifold numbers. Any advice on hooking up this exhaust system would be appreciated.
Since you will need to have a custom exhaust made up, you really should invest in some quality headers as well. Headers plus a nice dual set of pipes will improve your performance.
